Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a control system for a power supply for an intelligent lock in view of the above deficiencies. The short-circuit problem caused by the internal diaphragm of the battery greatly reduces the requirements for the battery, thereby reducing the cost of the battery, and adopts a dual power supply system. If the battery is dead, an external backup power supply can also be connected to unlock the lock.

Abstract

The invention discloses a control system of a power supply for an intelligent lock. The control system comprises a battery charging module, the battery charging module comprises a chip U1 and a chip U2, and the model of the chip U1 and the model of the chip U2 are TP4057. The system has the advantages that the quiescent current is extremely low, the actually measured quiescent current is smaller than 1 microampere, the problems that the temperature of the battery rises rapidly due to large current and a short circuit is caused to an internal diaphragm of the lithium battery due to overheatingare solved, the requirement for the battery is greatly reduced, and therefore the battery cost is reduced; a dual power system is adopted, and if the battery is out of power, an external standby powersupply can be used for unlocking.

Description

technical field [0001] The invention relates to a control system of a power supply for an intelligent lock, belonging to the technical field of electronic control. Background technique [0002] The emergence of fully automatic locks has greatly improved the intelligence of door locks, especially when installing fully automatic smart locks, there is no need to replace the lock body, it has a wide range of adaptability, and is easy to operate, so it is welcomed by consumers, so it has become The new darling of the smart lock industry. [0003] However, judging from the use of fully automatic smart locks purchased by consumers at present, the prospect is not optimistic. Due to many small problems, high failure rate, and great complaints from consumers, many large-scale smart lock companies are not optimistic about this high-end smart lock. Products are daunting. [0004] The service life of the battery is short and it is easy to be damaged. Generally, the manufacturer is equi...
